Hi,
I posted this question on BeagleBone group, but there is no reply to my question. I hope that somebody here can help.
I see the following message from a link:
root@bbb-deb:~-- $ ls -l /sys/class/leds/beaglebone:*:*/brightness
-rw-r--r-- 1 root root 4096 Nov 22 13:35 /sys/class/leds/beaglebone:green:usr0/brightness
-rw-r--r-- 1 root root 4096 Nov 22 13:35 /sys/class/leds/beaglebone:green:usr1/brightness
-rw-r--r-- 1 root root 4096 Nov 22 01:30 /sys/class/leds/beaglebone:green:usr2/brightness
-rw-r--r-- 1 root root 4096 Nov 22 13:35 /sys/class/leds/beaglebone:green:usr3/brightness
It is the first time I see ':' in a path. Whether is it just like a general character in the path, or having special meaning?
I am new to Linux yet, though using for some time.
Thanks,
